11. Ideal Brayton cycles also have an ideal efficiency equal to ideal Carnot cycle efficiency. 12. A real engine ( left ) compared to the Carnot cycle ( right ). 13. Perucca once demanded that a student describe the Carnot Cycle during an oral examination. 14. So more heat is given up to the cold reservoir than in the Carnot cycle . 15. He first experimented with a Carnot Cycle engine, and then developed his own approach. 16. MFCs use energy more efficiently than standard internal combustion engines, which are limited by the Carnot Cycle . 17. This is because of limitations of generating usable work from difference in heat as per the Carnot cycle . 18. The paper outlined the basic energetic relations between the Carnot engine, the Carnot cycle , and motive power. 19. Figure 2 : A Carnot cycle acting as a heat engine, illustrated on a temperature-entropy diagram. 20. This implies that there is a function of state which is conserved over a complete cycle of the Carnot cycle .
